LISTER PLOW. 1

Application filed Dec ber a, 1924. Serial N6. 754,596.

To all whom it may concern."

Be it known that I, TURNn-Y of Texas, have invented certain new' and useful Improvements in Lister Plows, of which the following is a Specification.

This invention relates to plows, more partieularly has for one-of its objects to improve the construction and increase the efficiency. and

utility of devices of this character.

Another object of this inventionlis to provide a device of this character having. .means for coupling. two or more plows to operate in unison and with sufficient flexibility in the coupling to permit operation over uneven ground, and also withthe parts so arranged that one of the plows operated singly. 1

With these and other objectsin view;

of construction as hereinafter shown and tive of the preferred embodiment. of the invention.

the axle being in transverse section.

The. improved device includes a two-part arched axle 10 and 11 flexibly united by a universal joint, represented conventionally at 12. Theaxle section 'lO earries. spaced porting frames and one ofthe axle sections,

bearing wheels13 and 14, while .the axle 7 section 11 carries asingle wheell5. of] the class of lister plows,.and 4 One side member of the universal joint 12 18 coupled to the inner terminal of the axle 10,"while, the other side memberis coupled to a stub axle "16, and th adjacent p m be adj ustably coupled thereto, for instance by set screws=18.. By this arrangement the axle section 11 and its attachmentsmay be adjustedtoward and away from the axle 1 section 10 within the range of the stub axle. to vary the distance between the listen Rigidly attached to thever of the arched axle 10 is alsubstantially. U} shaped frame including spaced sideportions '1920 and lateral rear connecting portions tical portions 21, while a like v U-shaped frame, including spacedside'portions 22 23 and rear lateral portion 2 1, is rigidly coupled to the vertical j portions' of. the arched' ax le 11. The. forare connected'by'clips 25 :and 26 to the Ward'je'nds of the frame members 19 and'20'.

vertical portionsi'of the axle 10, whilethe forward ends of "the frame members 22 and] "23 are connected by clips 27 and 2am the .-vertical portions of the axle.11.

The draft tongue is represented asga whole 3233, and'conneeted at, 34.'j35-'36 and 37 to the bars at their ends are short bars 3839 in; spaee'di'parallel relation to the tongue, I

At its rear end the memherBS is coupled 'fto the frame members-2223 by an inverted? substantially U-shaped standard 48, while a similar standard 42 couplesv the member I Obliquely directed braces 44 and are respectively connected at their ends to the members 19 and 20 and 39, while like Y braces E16 and 47' are connected at theircnds to the members 22Iand'23fand the member 3 8.- One of the bolts or rivets of each of the the seat standard 64 is connected clips 2526-27 and 28 will preferably be utilized to attach the standards 41-2 and 513 and the braces 4el-45-46 and 17, to the members 1920 and 22-23.

By this arrangement the tongue frame and the axle frames are rigidly united.

Attached to the transverse portions 21and 24 of the frames are bracket devices and as they are precisely alike the description of one will suffice for both.

Each of the brackets comprises a vertical body 48 having means for attachment re spectively to the portions 21 and 24 of the frames, and each also including avertical socket 49 and spaced. reinforcing webs 5051, the latter having a downwardly opening seat 52.

A shaft or standard each including a vertical portion 53, is rotative in the socket 1-9, and a rearwardly directed oblique portion 5 1 terminating in a bracket including a bearing 56 in which stub axles 57 are rotatively mounted, the latter each carrying twin trailer wheels 57.

Attached to the oblique portions 5 1 of each of the trailer wheel standards is a two part bracket device 59 and 60, having rearward extensions 59 and 60 bolted or otherwise connected at 61. The portion 60' of the bracket is provided with upstanding ears 62 in which a roller 63 is mounted and bearing when the standard extends directly.

cally.

The vertical portions 53 of the standards extend above the portions 50 of the brackets, and slidably disposed upon these extendec portions is a bridge member 64 to which and carrying the seat 65.

A spring 66 surrounds each of the vertical portions 53 of the standards between the bridge member 6 1 and the portion 50' of the bracket, and operates to mutually support the standards and trailer'wheels relative to the supporting frames.

The plow beams are represented respectively at 67, and each are coupled which a mold board 69 is attached, as

adjustably to a member 68 to double shown. Attached at 70 to each of the members 68 is a clip device 71, each clip device having a bracket device 73 pivoted thereto at 72. Each of the devices 73 includes'a bearing 74 to receive a standard 75 adapted to be adjustably supported in the bearings by a set screw.76. At its'lower end the standard 75 is provided respectively with a bearing 77 to support a stub shaft 78, the latter carrying an obliquelydisposed dish shaped coverer disk 79.

Each ofthe plow beams 67 hassecured nected to each of the link members 96 and extending rearwardly therefrom, isa spring 97 which is attached at its rear end to the standard 97 and acts to hold the plow beam 69 in contact with the earth at all times. The shaft 92 is mounted in bearings 91 which are secured to the side beams'l920 and 22-23 respectively, of the Ushaped frames.

Extending upwardly from each of the plow beams 67 is a pair of supporting standards 99 which support the seed pan structure and the drive mechanism or chains 87 connected therewith. A supporting arm 100, having one end connected to the seed pan structure 85 carries upon its other end a sprocket wheel 101 over'which the chains 87 pass and a second arm 102 extends from and assists in the support of thesprocket wheels 101, to the frame axle'where it is mounted to oscillate thereon.

It will be seen that upon moving the lever 93 forwardly for instance, the shaft 92 will be revolved and the link members 96 swung forwardly and downwardly the plow beam and seed pan structure and as sociated parts will be swung forwardly at the same time thus lifting the plow 69 from the ground. The spring 97 acts to maintain positive contact between the plow 69' and the ground, when the lever 93 is drawn backwardly.

At their forward ends the plow beams 67 I are provided with clevis devices 80, and

coupled to the clevises by link devices 81 1s a draft beam 82, and coupled to the draft beam by a link device 83 is an evener beam 84:, the latter designed to supportthe draft appliances, not shown.

1 The seed cans are represented convention- .ally at 85, the seed dropper mechanism at 86 operative by chains 87 from the aXies, and the seed spouts at 88, pf the usual construction.

7 The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages;

Having thus described the invention, what is claimed is: V l
